Watch the Documentary That Inspired Johnny Knoxville's 'Action Point'

What do you get when you combine Jackass and Adventureland? Johnny Knoxville’s new comedy, Action Point. But the movie isn’t just a clever idea to make a summertime release with dangerous stunts performed at an amusement park, wrapped inside a fictional plot. Action Point is actually based on a true story.

In our interview with Knoxville, he admits to being inspired to make Action Point after seeing the 2013 documentary short titled The Most Insane Amusement Park Ever. The 14-minute film, made for Mashable by Seth Porges and the people at DailyMotion, tells of the legend and the reality of Action Park.

For those who didn’t live in the New York City area and haven’t heard of this place, Action Park was a water park in New Jersey with a deserved reputation for being the deadliest, most dangerous theme park ever. Not only did a number of people die there, but countless visitors were injured in its decades of existence.

The Most Insane Amusement Park Ever features former employees of Action Park, some of whom now run the place under a new name (and more safely), as well as comedian Chris Gethard and various Mashable writers sharing their memories of such attractions as the skin-scraping Alpine Slide, the impossible looping water slide and more.

Watch the documentary below and then check out Action Point for the slightly exaggerated fictionalized version of the story in theaters this Friday.
